1553H-25.000D33ATSK

Overview

The 1553H-25.000D33ATSK is a quartz crystal oscillator manufactured by Suzhou Hangjing Elec & Tech Co., Ltd. It operates at a frequency of 25 MHz with an HCMOS output interface and a supply voltage of 3.3 V. The device features a stability tolerance of ±75 ppm. It is housed in a compact 5032 surface-mount package, specifically a 4-VDFN (3.2x2.5 mm) configuration. This component serves as a precision timing source for digital circuits requiring stable clock signals.

Feature Summary

• Generates a precise 25 MHz clock signal using HCMOS logic levels
• Operates on a standard 3.3 V power supply rail
• Utilizes a compact 4-VDFN surface-mount package for space-constrained designs
• Maintains frequency stability within ±75 ppm tolerance

Applications

• Digital system clock generation
• Microcontroller timing sources
• Communication interface synchronization
• Consumer electronics timing circuits

Procurement Notes

Verify the specific suffix 'D' against official datasheets to confirm the exact stability grade and packaging type. Ensure the 3.3V operating voltage aligns with target circuit requirements. Confirm the 5032 footprint dimensions match PCB layout constraints before finalizing procurement orders.

Selection Notes

Select this model when a 25 MHz HCMOS clock is required with moderate stability. The 3.3V specification suits modern low-voltage logic families. The 4-VDFN package offers a balance between thermal performance and board space efficiency compared to larger through-hole alternatives.

Part Context

This oscillator belongs to the 1553H series from Suzhou Hangjing, which focuses on quartz frequency control components. The series includes various frequencies and packages, serving industries like smartphones, tablets, and in-vehicle systems. The company emphasizes precision supply chains and rigorous testing for consistent quality across its product line.

Replacement Considerations

Direct substitutes must match the 25 MHz frequency, HCMOS output, 3.3V supply, and 5032 package. Verify that alternative parts offer equal or better stability (±75 ppm). Check pinout compatibility and thermal characteristics to ensure seamless integration into existing designs.
